I need to be able to access the vertex information stored in a morph target.
When you import a mesh with a morph target on it from Max or Maya the shapes show up as slider values on the object. The sliders are attached to simple AnimatableDouble properties, and do not appear to plug into anything that looks remotely like stored vertex information.
Does anyone know where the vertex data for shapes is stored and how I would go about accessing it?

which version MB you are using?

There is no access to the shape vertex info in MB2010 and before versions. In MB2011 there a set of FBModel::ShapeXXXXXX() functions to do so.
